Letters Patent No. 96,623, dated November 9, 1869.

GAS HEATER.

The Schedule referred to in these Letters Patent and making pax-t of the same.v

To all whom it may concern:

Be it known that I, EILERT O. SCHARTAU, of the city of Philadelphia, and State of Pennsylvania, have invented new and useful Improvements in Heaters to be Attached to Lamps orGas-Burners; and I do hereby declare the following to lie an .exact description thereof, reference lbeing.; had to the accompanying drawings, and to the letters of reference marked thereon, making a part ot' this specification. l

It is a. tubular kettle, having hot-air chambers, where the. heat may condense and act upon an eX- tended surface. In order to further accelerate the boiling, and operate a speedy. and complete reduction of the essential oil and aromatic qualities ot the ground coffee, this latter is encased in a hollow ring, which is connected with the lid of the kettle by a wire. `This receptacle, by its position, having three sides of it in close Contact with heated surfaces', is thus made the focus or cent-re of the heat produced.`

Figure 1 represents the kettle A and the connecting-plate B, which partly forms athe lower -hot-air chambers, the whole resting upon thelower half of a jointed glass chimney, X. V

C is the central pipe, support-ingr onv its top the lid I), this latter havincv an aperture, J, which is considerably smaller than the pipe, forming thus a chamber for condensed heatin the very centre ofthe kettle.

With the object of utilizing the heat escaping from the draught-hole .I of the lid D, and to create an up per chamber of heat, N, a lid, E, rests upon a ange at the top of the kettle, and 'a little above the orifice of the lid D.

Below, above, around, and at its centre, the kettle has chambers for condensed heat 'N N N N.

lr fr are draught-holes.

G, the receptacle' for ground coiee, is a perforated hollow ling, with its lid downward, and connected with the lid D by a wire, k. l

When this heating-apparatus is to be used in counection'with a gas-burner, the lower half of the jointed glass chimney X is attached, by a. metallic hoop, I, to the supporting plate M.

Figure 2 represents the receptacle G, as seen at'g. l. l

' Figure 3 represents acone-shaped cover for the centrai pipe C.

What I claim as my invention, and desire to secure by Letters Patent, lis- 1. The tubular coiee or tea-pot, with hot-air chambers.

2. The combination of this kettle with the lower half of the jointed glass chimney for lamps andl gasburners, and also of the holder or receptacle for tea. or ground coffee, which is attached to the said kettle in jthe manner and for the purpose herein set forth and specified.
